What Is Indexed Universal Life (IUL)?
Indexed Universal Life (IUL) is a type of permanent life insurance that combines a death benefit with cash value growth linked to a stock market index, featuring a floor that protects against losses.
How an IUL Works
An IUL policy provides a permanent death benefit plus a cash value component. The cash value earns interest based on the performance of a market index (usually the S&P 500), subject to a floor and a cap.
The floor (typically 0%) means your cash value never decreases due to market losses. The cap (typically 9-14%) limits the maximum credit in any period. You get market upside with downside protection.
Key Features
IULs offer several features that distinguish them from other life insurance types:
- Flexible premiums — pay more in good years, less in lean years
- Tax-deferred cash value growth
- Tax-free policy loans for supplemental retirement income
- Permanent coverage — no expiration date
- Living benefit riders for terminal or critical illness
Who Is an IUL Best For?
IULs work best for people with long time horizons and goals beyond basic income replacement: business owners building tax-advantaged reserves, high earners supplementing retirement savings, or parents building a legacy asset. They are not ideal for short-term needs or purely budget-conscious coverage.
Frequently Asked Questions
- What is the difference between IUL and whole life?
- IUL has flexible premiums and market-linked growth with a cap and floor. Whole life has fixed premiums and guaranteed (but lower) cash value growth. IUL offers higher growth potential with more complexity.
- Can you lose money in an IUL?
- Your cash value cannot decrease due to market performance because of the 0% floor. However, policy fees and cost of insurance charges are deducted regardless of market performance.
- How are IUL policy loans taxed?
- Policy loans from an IUL are generally not considered taxable income. However, if the policy lapses with an outstanding loan, the loan balance may become taxable.
- What is the average return on an IUL?
- Historical average credited rates typically range from 5-8% annually, though this varies by carrier, index strategy, and market conditions. The floor and cap structure means returns are more moderate but more stable than direct market investment.
